Hi John,
I recommend you take note of the history of the device because based on your typing, I believe you are lagging behind the line of progress.
Please go to my web page where I try to keep the topic fresh. Although I must admit it does not provide a complete overview either. Then it is worth reviewing the "Wiki" and "Files" pages of the forum, as the essence of what was said on the forum has been gathered.
If you still find a missing link after this, feel free to post in the forum.
